Dichroic Glass
These beautiful 925 silver bezel set pendants, earrings and rings catch and relfect the light.
Dichroic glass is glass containing multiple micro-layers of metal oxides which give the glass dichroic optical properties.
The invention of dichroic glass is often erroneously attributed to NASA and its contractors who developed it for use in dichroic filters.
Dichroic glass dates back to at least the 4th century AD (Lycurgus cup).
HOW DICHROIC GLASS IS MADE
Multiple ultra-thin layers of different metals (gold, silver), metal oxides (titanium, chromium, aluminium, zirconium, magnesium) and silica are vaporised by an electron beam in a vacuum chamber.
The vapour then condenses on the surface of the glass in the form of a crystal structure.
This is sometimes followed by a protective layer of quartz crystal.
A coating that is created is very similar to a gemstone and, by careful control of thickness, different colours are obtained.
